When my ninety-some-odd grandfather fell and we were told he was going to die of some complication or other of the broken hip (turned out to be pneumonia but we had about three days' warning), I wrote him a letter thanking him, and granny since she was still alive at the time, for being the kind of gparents they'd been, for raising Daddy to be the person he was, and a lot of other more personal things. Uncle Greg had time to read it to him before he died, and it made him (UGreg) cry buckets and buckets and I was soooooo glad I'd done it.

Don't know if I'd really make the effort for the famous folks who'd done wonders for me... they know.
